Infield fly rule after the fact

[jmkupka]

Not necessarily... the "ordinary effort" aspect of the rule is what brings umpire's judgement into the discussion, and which could prevent the possibility of protest.

A gusty day can turn a can o'corn fly ball over F1's head into a nightmare to catch, but still recoverable enough to turn a double play. Some would reverse it to be IFF.
But if that same dropped ball became a "safe all around" due to a panicky F1, we'd say play on, despite DC's complaints.
